tcxmail2.tcfcu.org. 30 71.4.123.37 [US] XO

At&t said we had to do this way, but it wouldn't route incoming email
when the first one is down. we only have the one email server

we have one exchange 2003 server and we use a External ISP T1

10 email.domain.org (First ISP IP address for the email server)
20 email2.domain.org (second ISP IP address for the email server)

We have a backup ISP connection that stays idle. when we switch over
to the backup ISP connection (because the first is down) we cannot get
the incoming email in. Outgoing works fine.

How can we get the incoming email to route to the one exchange server
with either ISP?


Does the backup ISP have the correct information to route the mail to
you?
